SiGe quantum wells implementation in Si based nanowires for solar cells applications

M. Safi, A. Aissat, H. Guesmi, Jean-Pierre Vilcot

This study focuses on modelling and optimizing a new Si nanowire solar cell containing a SiGe/Si quantum well. Quantum efficiency measurements show that the proposed structure has a higher energy absorption advantage and stronger than that of a solar cell based on a standard Si p-i-n nanowire. As a…

Fiber-tip spintronic terahertz emitters

Felix Paries, Nicolas Tiercelin, Geoffrey Lezier, Mathias Vanwolleghem, Felix Selz, Maria-Andromachi Syskaki, Fabian Kammerbauer, Gerhard Jakob, Martin Jourdan, Mathias Kläui, Zdenek Kaspar, Tobias Kampfrath, Tom Seifert, Georg von Freymann, Daniel Molter

Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost. However, current experiments and proofs of concept rely on free-space ultrafast pump lasers and rather complex…

Compact localized boundary states in a quasi-1D electronic diamond-necklace chain

S. Kempkes, Pierre Capiod, S. Ismaili, J. Mulkens, L. Eek, I. Swart, C. Morais Smith

Zero-energy modes localized at the ends of one-dimensional (1D) wires hold great potential as qubits for fault-tolerant quantum computing. However, all the candidates known to date exhibit a wave function that decays exponentially into the bulk and hybridizes with other nearby zero-modes, thus…

A Hybrid Uplink Multiple Access Method Based on NOMA and SDMA

Serdar Özyurt, Eric Pierre Simon, Murat Torlak

We introduce a hybrid uplink multiple access method with a multi-antenna base station (BS) and two naive single-antenna users. Both users with no channel state information (CSI) have low computational power and simultaneously transmit their information to the receiver on the same frequency band.…

Explainable root cause and pathway analysis with robust and adaptive statistics

Mohamed Amine Atoui, Vincent Cocquempot

Accurate detection of faults is desired to reduce risks and costs. The identification of the propagation path of faults and the system’s variables responsible of faulty operating conditions is also paramount. This paper presents a new alternative to a well-known Bayesian network-based approach to…

Acoustic Wave Generation in Nanofluids: Effect of the Kapitza Resistance on the Thermophone to Mechanophone Generation Mechanism Transition

Stefano Giordano, Michele Diego, Francesco Banfi

High frequency, short wavelength acoustic wave generation in fluids, by means of immersed nanotransducers, is key to applications ranging from the biomedical to the ICT sector, all the way to investigating fundamental aspects of the mechanics of fluids. In this context, the commonly adopted…
